Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
![# Haber-Bosch Process: Calculating Theoretical Yield of Ammonia
The Haber-Bosch process is used for the synthesis of ammonia (\( \text{NH}_3 \)) from its elements. This exercise involves calculating the theoretical yield of ammonia, in moles, from the complete reaction of 59.8 grams of nitrogen (\( \text{N}_2 \)) in the presence of excess hydrogen (\( \text{H}_2 \)) gas. The reaction follows the balanced chemical equation:
\[ \text{N}_2(g) + 3 \, \text{H}_2(g) \rightarrow 2 \, \text{NH}_3(g) \]
### Calculation Steps:
1. **Starting Amount:**
- Determine the amount of \( \text{N}_2 \) in grams.
2. **Equation Conversion:**
- Use the balanced chemical equation to find the molar ratio between \( \text{N}_2 \) and \( \text{NH}_3 \).
3. **Calculation Input:**
- The available starting amount in the illustration is 59.8 grams of \( \text{N}_2 \).
4. **Molar Masses:**
- The molar mass of \( \text{N}_2 \) is 28.02 g/mol.
- The molar mass of \( \text{NH}_3 \) is 17.04 g/mol.
5. **Stoichiometry Factors:**
- From balanced equation: 1 mole \( \text{N}_2 \) produces 2 moles of \( \text{NH}_3 \).
6. **Calculating Moles:**
- Convert grams of \( \text{N}_2 \) to moles.
- Apply stoichiometry to find moles of \( \text{NH}_3 \).
7. **Interactive Features:**
